326b2259b7 Move UCB-licensed code from 4-clause to 3-clause licence. 
Patches provided by Joel Baker in PR 22366, verified by myself.

134561f7df - convert header() away from a signal function (it does all sorts of stdio 
and more) and use a little sig_header() helper.
- in selectdrives() make sure we don't overwrite some arrays.  this makes
"iostat 1" work again on my really wide screens where defdrives (number that
can fit) was > ndrives (number of drives), rather than dump core trying to
print (char *)1...

c71be29ffd Use the terminal width to choose the default number of drives listed. 
Suggested by matt green and (indirectly) enami tsugutomo.

329fb18071 Pinch code from vmstat to get the number of lines of the terminal, and 
show the header once per screen instead of fixed at every 22 lines.

2f35689ef7 Bump the width of the MB/s and t/s fields and show only 3 drives by 
default.  The default display now fits in 80 columns, and looks much
better on modern systems.

70378aeac7 - Account the number of lines consumed so that -xw displays header 
frequently enough.
- As we are initializing dk_select to 0 (via dkinit), no need to check it.
- Re-order the code in display() to highlight the fact that -x is
  exclusive with others.
- If user really specified some drives and none of them are found,
  just bail out rather than falling back to default behaviour.
- Other misc. cosmetic changes while I'm here.

3cf4c73d05 iostat(8) and systat(8) support for separate read/write disk statistics. 
"iostat -x" now shows these (ala linux/solaris), but this is only splitting
the read/write bytes/transactions, not adding any new metrics.  "systat
iostat" now has two new commands to switch between combined/separate mode
for both it's numbers & bar modes.

f80c7eebd7 Since the KERN_CP_TIME sysctl reports total clock ticks across all 
cpus and hz is measured in ticks per cpu, divide tick count by ncpu to
determine elapsed time since last sample.

Fixes I/O rate deflation observed on multiprocessors.

f28c3652ea Use " %2.0f" instead of "%3.0f" to print out the CPU percentages - this 
way 100 in a column doesn't merge into the previous column.

c847b03d13 Kb' means kilobits, Mb' means megabits. Since we're talking about bytes, 
not bits, use the uppercase `B' when reporting statistics, and be explicit
about it where appropriate.  Noticed by J.T.
